In the current breeding practices, management of the estrous cycle is a common. Breeders want to know when their mare is in one phase or the other and also wants to be able to determine when she will ovulate. Manipulation of the estrous cycle is a practice of breeding management. Manipulation of estrous involves changing the normal cycle through hormone treatments or other methods. Managing and manipulating the estrous cycle allows breeders to have control over the phase the mare is experiencing
I. The Edvidence of Fossils A. (28-1) The Formation of Fossils 1. Fossil: The actual remains or any trace of an organism that lived at some time in the past. 2. Petrifaction: The process by which the body of a dead organism is slowly replaced by dissolved minerals. 3. Mold: A rock as a hollow form; Cast: A copy of the external form of the original organism. 4. Imprint: A type of fossil formed when an impression made in mud by a living thing is preserved when the mud is transformed into rock. B
Introduction Aspirin is one of the most commonly used drug in the world. The generic name is acetyl salicylic acid and the drug belongs to the group of non- steroidal anti-inflammatory medicines, which works by inhibiting the production of compounds in the body that cause pain, fever, inflammation, and blood clots (Koester, 1993. Aspirin is also a member of the salicylate family of compounds as it synthetized from salicylic acid, which was discovered in oxford (UK) by Edward stone in 1793 and first
Prostaglandins are formed by the enzymes COX1 or COX2. The prostaglandins produced by COX1 are generally responsible for the maintenance and protection of the gastrointestinal tract, kidneys, and other organs. The prostaglandins produced by COX2 are predominantly known to cause inflammation and pain responses. NSAIDs work by primarily inhibiting the formation of prostaglandins by the COX2 enzyme. As the formation of the prostaglandins produced by COX2 diminishes, pain
that it achieves some of its effects by hindering the flow of prostaglandins. Prostaglandins are hormone-like substances that influence the elasticity of blood vessels. John Vane, Ph. D., noted that many forms of tissue injury were followed by the release of prostaglandins. It was proved that prostaglndins caused redness and fever, common signs of inflammation. Vane's research showed that by blocking the flow of prostaglandins, aspirin prevented blood from aggregating and forming blood clots
mode of action is to reduce the production of prostaglandins. Prostaglandins are hormones which trigger pain and inflammation in the immediate damaged area. NSAIDs inhibit an enzyme, Cyclo-Oxygenase (COX), which is involved in the first stage of prostaglandin production. There are two variants of this enzyme; COX-1 is responsible for the normal every day production of prostaglandins whereas COX-2 is responsible for production of additional prostaglandins when the body is injured as a natural defensive
Transposition of the Great Arteries is when the aorta and the pulmonary artery are switched. It is also know as TGA or congenital defect. “Transposition means the displacement of a viscous to a site opposite from that which it normally occupies” said by the Merriam-Webster medical dictionary. TGA is a congenital defect which means it is present at birth. The arteries being switched causes there to be two different blood flows instead of one. The body receives deoxygenated blood and the lungs receive
PHYSIOLOGY FOR HEALTH SCIENCES 3 ASSIGNMENT 1 1(a) Define the term “endocrinology” (1) Endocrinology is the study of the endocrine system and secretion of hormones with its different diseases. It is concerned with developmental events such as growth, differentiation, and the psychological or behavior of tissue function. Activities of hormones in sleep, digestion, respiration, excretion, mood, stress, lactation, movement, reproduction is involved . 1(b) Discuss the different classes of hormones
Possible complications include infection, cervical laceration and uterine perforation. Mifepristone: also known as RU-486, the chemical causes an abortion by interfering with the function of the placenta, starving the unborn child to death. Prostaglandins are then administered to expel the fetus. This method of abortion takes place over the span of several days; the average woman using it bleeds heavily for more than nine days, but some women have bled for over four weeks. Mifepristone is just
the pliers until there is only the head left. The skull of the head is then crushed and pulled from the uterus. The nurses must check that all the body parts have been removed and none have been left in the uterus. Prostaglandin Abortion involves the hormone prostaglandin, which induces labor. The trauma of the birth usually kills the baby,
Osteoporosis is a silent, complex, multifactorial, chronic disease characterized by the progressive loss of bone density, which leads to the risk of imminent fractures (1). Osteoporosis "Osteo" is Latin for bone. "Pores" means "full of pores or holes." Thus, osteoporosis means "bones that are full of holes"(1). The bone mass reflects the balance between formation by osteoblasts and resorption by osteoclasts. Around the third decade of life the peak bone mass is reached, and then begins a slow process
Prostaglandins contribute to peripheral sensitization by binding to G-protein coupled receptors that increase the levels of cyclic AMP within nociceptors. Prostaglandins also reduce the threshold depolarization required for generating action potentials by phosphorylating a specific class of TTX-resistant sodium channels, TTX-R Na+, that
In today’s world, acetaminophen also known as Tylenol, is known to be remarkably popular drug in many countries [1]. This type of drug is known to be an analgesic and antipyretic [1]. In other words, it helps relieve pain associated with many conditions as well as reducing fever [1]. Acetaminophen can be used for many purposes, such as the relief of headaches, muscles aches, toothaches, and etc [1]. On the other hand, this drug may also be used for purposes that are not listed on the medication guide
Introduction- What is Etoricoxib? Etoricoxib, also known as Arcoxia1, is more commonly known as a non-steroidal anti-inflammatory drug (NSAID), or as a cyclo-oxygenase-2 inhibitor (COX-2). Therapeutically, it is specified for the ‘symptomatic relief” of conditions such as osteoarthritis (OA), rheumatoid arthritis (RA), ankylosing spondylitis2,3, and overall for their analgesic and anti-inflammatory properties. Arthritis is a chronic disease affecting up to ten million people in the UK. Approximately
Sepsis is defined as an exaggerated, overwhelming and uncontrolled systemic inflammatory response to an initially localised infection or tissue injury, which may lead to severe sepsis and septic shock if left untreated (Daniels, 2009; Robson & Daniels, 2013; Dellinger et al, 2013; Perman, Goyal & Gaieski, 2012; Vanzant & Schmelzer, 2011). Septic shock can be classified by acute circulatory failure as a result of massive vasodilation, increased capillary permeability and decreased vascular resistance
Introduction Acetaminophen, also known as Paracetamol, is an organic compound that is commonly used as a medication for pain and fever relief. It has been around for a while and is found under several different brand names around the world. With research, the chemistry behind acetaminophen can be discovered as well as its practical applications, its adverse effects to society and the environment, and other information surrounding this compound. The History In the middle ages, Antipyretic agents
2). - Digoxin (Lanoxin): Increases serum potassium along with Piroxicam, interaction is possible. - Paracetamol (Acetaminophen): “Decreased effectiveness of diuretic (Furosemide) because acetaminophen may decrease renal prostaglandin excretion and decrease plasma renin activity”(Woo & Wynne, 2011, p. 891). - Piroxicam (Feldene): Combining with diuretic (Furosemide) in elderly patients, volume-depleted, or with poor kidney function can result in reduced kidney function and lead
Prostaglandin release stimulates uterine contraction, which cause the baby to move down the birth canal and weaken the membranes. Metalloproteases initiate the degradation of the chorion and amnion that inevitably cause them to rupture. Preterm chorioamnionitis
Kidney Failure and Ultramarathoning Four days after winning the Seagate 100 km Ultramarathon in Toledo, Ohio, I was hospitalized for 11 days with Acute Kidney Failure, a direct consequence of the race, possibly exacerbated by the 2400 mg of ibuprofen that I took during the race. In this article, I will describe my race and my hospitalization, discuss similar experiences of two runners after the 1994 Western States (WS) 100 Mile Endurance Run, and tell what I have learned that might be of general
SELECTION OF DRUG Aceclofenac is a non-steroidal anti-inflammatory drug, widely used in the management of osteoarthritis, rheumatoid arthritis and ankylosing spondylitis. Usual therapeutic dose is 100 mg twice daily and half life is 3-4 hrs; thus it is necessary to be administered frequently in order to maintain the desired concentration. Therefore, Aceclofenac is an ideal candidate for sustained release formulation, resulting in more reproducible drug absorption and reducing the risk of local irritations
